I paid $99 for the excursion. This included the bus (short ride) to the ferry to De Palm Island in Aruba and the same back to the ship. Once at De Palm Island (about 3 1/2 hours) I had use of the facilities, open bar (sodas and alcoholic beverages) and lots of food (island buffet and a grill). The Snuba consisted of a on shore lesson, a comfort zone time period in the water and about a half an hour dive, I also had use of snokel gear.
